Not able to Bind framebuffer for a floating point texture

[JH2012]

Hi, Guys! I am a newbie in OpenGL es, currently dabbled in the GPU image processing. When I am trying to create a framebuffer to load half float point texture, it always fails. Does anybody know why?
Thanks~

Code: Select all

glGenFramebuffers(1, &framebuffer);
	glGenTextures(1, &texture);

	glBindTexture(GL_TEXTURE_2D, texture);
	glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, texWidth, texHeight, 0, GL_RGB,   GL_HALF_FLOAT_OES, NULL);

the program is alright when substitute GL_HALF_FLOAT_OES with GL_UNSIGNED_BYTE

Floating point (and half-float) texture formats are not supported by the GPU on the Raspberry Pi.

Thanks! As the glGetString(GL_EXTENSION) returns OES_texture_half_float, I thought it would work for me.

GL_OES_vertex_half_float is supported, OES_texture_half_float is not.
